A Longitudinal Analysis of Electronic Cigarette Use

Wednesday, April 9, 2014Posted by: Natalia Gromov

Although electronic cigarettes (e-cigarettes or electronic nicotine delivery systems) are aggressively promoted as smoking cessation aids, studies of their effectiveness for cessation have been unconvincing. One randomized trial comparing e-cigarettes with and without nicotine with a nicotine patch found no differences in 6-month quit rates. Population-based, longitudinal studies have also not shown associations between e-cigarette use and quitting. A longitudinal, international study found that, although 85% of smokers who used e-cigarettes reported using them to quit, e-cigarette users did not quit more frequently than nonusers (P = .52). Among US quitline callers, ecigarette users were less likely to have quit at 7 months than nonusers.
